r 4' I I having two members interlocking with said ratchet to permit its movement in a predetermined direction and prevent its movement in a reverse direction, and means for actuating said pawl to cause one or the other of said members to interlock with said ratchet.

3. In a device of the character stated, the combination with the engine reverse lever, of a ratchet wheel connected therewith, a pawl interlocking with said ratchet wheel to permit its movement in one direction and prevent its movement in a reverse direction, and electromagnet means controlling said pawl, a source of electric supply, and means to close the circuit through said electromagnet means.

4. In a device of the character stated, the combination with the engine reverse lever, of a ratchet wheel connected therewith, a pawl having members alternately interlocking with said ratchet wheel, electromagnets controlling said pawl, and means for closing the circuit through either of said magnets whereby one pawl member is engaged with said ratchet wheel and the other pawl member is disengaged from said ratchet wheel.

5. In a device of the character stated, the combination with the engine reverse lever, of a ratchet wheel connected therewith, a pawl having members alternately interlocking with said ratchet wheel, electromag- Gopies of this patent may be obtained for five cents each, by addressing the nets controlling said pawl, means for closing the circuit through either of said magnets whereby one pawl member is engaged with said ratchet wheel and the other pawl member is disengaged from said ratchet wheel, and means to retain said pawl in neutral position.

6. In a device of the character stated, the combination with the engine reverse lever, of a ratchet wheel connected therewith, a pawl interlocking with said ratchet wheel to permit its movement in but one direction, an electromagnet on each side of said pawl, a source of electric supply, a tension device for normally maintaining said pawl in inoperative position, and means for normally closing the circuit through either of said magnets.

7. In a device of the character stated, the combination with the engine reverse lever, of a ratchet wheel connected therewith, a pawl interlocking with said ratchet wheel to permit its movement in but one direction, an electromagnet on each side of said pawl to move the latter in one direction or the other, a source of electric supply connected with said magnets, and a switch on the bridge of the ship to close the circuit through one or the other of said ma ets.
